    aarch64: Make `VECTOR_TYPE_none` an enum member
    
    Change `VECTOR_TYPE_none` from a preprocessor macro to an enum member of
    `vector_type_index`
    
    gcc/ChangeLog:
    
            * config/aarch64/aarch64-acle-builtins.cc (VECTOR_TYPE_none):
            Delete preprocessor macro.
            * config/aarch64/aarch64-acle-builtins.h (VECTOR_TYPE_none): Add
            enum member.
